6 Claims.

This invention relates to a rigidly supported cord holder of a novel bodily demountable type, and more especially pertains to a wide range stanchion unit of moulded rubber compound or equivalent vulcanized plastic adapted to yieldably follow up a suspended conductor cord that supplies heating current to an electric sad-iron or the like shiftable appliance and which anchored stanchion is arranged to take up excessive cord slack when such applianc is operatively moved toward the stanchion.

The object of the present improvements is to devise an inherently simple, low cost holder unit of the indicated character including clampable means provided with anchoring devices permanently embedded into the butt end of an erected moulded stanchion of vulcanized material, and particularly one adapted to resiliently and adjustably sustain an overhead cord above the top board face of a clamped ironing table so that garments may be unobstructedly ironed thereon without interference from excessiv sag, kink or the like cord entanglement and which clamp means together with its aflixed stanchion may be conveniently detached from the table board for independent stowage.

The structural embodiments and advantages thereof will be made apparent by the accompanying two sheets of drawings, in which:

Fig. 1 in partial cross section represents a tubular sectionalized style of our cord holder assembly operatively clamped at the end of an ironing board, while Fig. 1A represents alternative means for binding the stanchion butt.

Fig. 2 is a fragmental elevational side view of a stanchion mounting bracket, and Fig. 3 is a transverse top view taken along line 33 of Fig. 1.

Fig. 4 depicts in perspective a clip fitting that may serve to reenforcingly trim th respective stanchion ends.

Fig. 5 shows a modified style of holder assembly having an embedded cord moulded therein, and Fig. 6 is a transverse top view taken along line 66 of Fig. 5.

Referring more specifically to Figs. 1 to 4 inclusive, I0 denotes a fragment of a wooden or metal ironing board having superimposed thereon the usual cushioning pad ll that may be retained in place by the fabric cover [2 whose inturned hem may be provided with an endless retaining elastic l3.

Suitable anchoring means for our holder may be fabricated as a U-shaped sheet metal bracket stamped to comprise a pair of mated upper and lower jaw flanges I5 and I6 that are integrally interconnected by a web component IT. A centrally apertured lip It may be struck out of the web stock as shown. Said web may be additionally perforated for a latch receiving aperture 19 and also be laterally reenforced by raised ribs such as 20. spring stock may have one leg thereof secured to the bottom flange and the other leg entered through the web to terminate in a depressible trigger 22'. Said other leg may be provided with a retractible shoe interposed to firmly clamp the board faces between the bracket jaws.

Attention is now directed to our unique lower stanchion section 23 that may be moulded in one piece from vulcanized rubber compound or the like plastic into a truncated columnlike shape, preferably of the conical frustum or pyramid type that is tapered and may have a cylindrical cavity 24 formed through the axis thereof. Each such flat stanchion end may be capped by a suitable metallic clip fitting 25 (see Fig. 4), which may comprise a tapped metallic plate or the like planiform element 26 of which one face may be provided with a centering tit. The opposed plate face is shown provided with a series of upturned relatively long grip prongs such as 21 that may be transversely perforated as at 28. Under the usual vulcanizing pressure and temperature, the fiow of hot rubber compound while being moulded, is intended to firmly embed and permanently bond the grip prongs against release. Said plate element may be centered into the apertured web lip l8 and have a round mouth tubular nut or the like demountable secur'ement 29 applied to hold said stanchion in a normally erected position.

It will be observed that the reversely embedded prongs 21 of the similar fittings 25 shown in Fig. I may be disposed in axial alignment whereby the fibers of the interposed vulcanized material are subjected to direct tension or compression stress when the stanchion is laterally deflected. Because of the inherently low torsional strength of such rubber compound, a spiral or the like circuitous interconnecting path between said prongs would prove inept for present purposes because said material would have torsional rather than the desired tension stress imposed thereon. For most effective results, such plastic requires a different mode of treatment and end securement from a helical spring of steel wire or the like closely coiled agency of fissured material; in our stanchion, the fiber stress is solely directed A hairpin type of latch 2| of flat lengthwise of the prop axis and counteracted by solid bulk material free from such fissure.

Essentially the composite bottom fitting 25 constitutes one style of butt retaining or binder means, it being obvious that as an equivalent, a special hexagon washer 26A or the like means without prongs, may be bodily embedded inwardly of one end of our rubberized prop 23A in the Fig. 1A manner.

In each such alternative, the plastic bulk material constitutes the sole securement between mated cap fittings.

The upper or crown end of the lower section 23 may be capped by a similar clip fitting 25 and have screwed therein an extension tube or upper metallic stanchion section 30 of which the tip may be lined with a guide bushing 3|. A twin conductor cord 32 may be shiftably threaded through the axial cavity 24 and retained against unwanted slip by a snugly fitting bushing and nut. The resulting frictional drag allows a long extension cord to be adjusted for proper sag requirements by longitudinal shift when one end of the prop suspended cord is plug connected to the sad-iron as intended. The upper bracket jaw is preferably secured to the socalled rear end of the ironing board and the sagging cord given sufiicient initial slack to reach a contiguous board face region when the iron is operatively reciprocated through a comparatively short stroke. For more distant operations, the cord slack will intermittently be taken up and whereupon the taut cord causes the sec tionalized prop to tilt forwardly into the deflected position 23 indicated by dotted outline in Fig. 1.

When moulded to nicely sized butt and crown dimensions, the inherent elasticity of our plastic stanchion section 23 is such as to freely yield laterally without exerting an inordinate counterpull on the sad-iron; also to automatically return and lift the slackened cord into its erect stanchion position. Such resilient action is preferably confined to the lower section 23 to leave the relatively stiff upper section rectilinear when the base section is laterally flexed. The upper section may be kept to a length that will best suit board requirements. Because of the cited cord shifting provision, a comparatively short overall prop length may still be made to reach all portions of the upturned board face. Such prop disposition allows of keeping its resilient lower section to a reasonably short length which in turn results in a sparing requirement for the relatively expensive rubberized material. At the contracted tip prop end, our crown cap may be neatly confined within the perimetric limits of it's flat crown face to avoid a cumbersome endwise connection with the superimposed section 30.

Upon completing the ironing operation, the trigger 22 may be conveniently depressed to bodily remove the assembled stanchion together with its suspended cord and its attached sadiron for stowage, it being the intent to independently market such stanchion and plug fitted cord as a universal unit without being associated with any particular make of standardized sadiron or ironing table.

Turning now to Figs. 5 and 6, there is here disclosed a modified embodiment comprising a covered ironing board 40 to which may be anchored a cross-sectionally U-shaped stamped bracket of sheet metal comprising an upper jaw flange or base plate 4|, a complementary lower jaw flange 42 and a pocketed interconnecting web component 43. The lower flange may be equipped with a clamping screw 44. Said web is purposely kept spaced with respect to the gripped board edge to inbuild a moulded Bakelite socket 45 in such spacing. The respective edge regions of said web may be integrally shaped to provide for a pair of inturned side ribs 46 whereby to reenforce said flanges against lateral spread when stamped up from relatively light sheet metal stock.

The upper jaw flange or prop anchoring means 4| may be provided with a medial aperture having an upstanding brim ridge 41 that is transversely perforated at 48 to constitute binding means. A series of additional grip prongs such as 49 may be struck out of said flange stock and transversely apertured as shown. In the present instance, a unitary stanchion 50 of vulcanized rubber compound may be moulded into a longitudinally tapered shape. This prop is neatly trimmed by an enlarged oval base contour 5! and permanently erected upon the upper jaw flange by embedding the interposed ridge or prongs in such plastic whereby to establish a rigid supporting bond for such base. The stanchion tip region 52 is here preferably given a gooseneck shape. Centrally embedded within the axial core region of the stanchion is a twin conductor cord 53 embracing the lead wires 54 and 55 of which the suspended terminal is plug connected to the sad-iron, as will be understood.

The upper jaw flange may also be impressed to provide for divergently raised channels such as 56 and 51 through which the insulated lead wires may respectively be carried to opposed terminal screws such as 58 and 59 of the inbuilt appliance socket 45. A substantially circular offset face 60 of said socket is preferably mounted to extend forwardly through a registering aperture 6| pierced in the bracket web, such socket assembly being secured in place by the riveted retaining clips 62 or the like. A mated detachable plug element 63 of a conventional extension cord 64 may at will be entered into the socket to supply heating current to the electric sad-iron (not shown).

As will be apparent, this alternative cord holder is otherwise intended to operate in an essentially identical manner with the Fig. l disclosure except that the all rubber stanchion is now moulded in one piece and the conductor cord being fixedly embedded throughout the length of said stanchion without provision for longitudinal slip adjustment. Upon completing the ironing operations, particularly when using an ironing table of the foldable leg type, the supply plug 63 may be detached from the socket 45. By loosening the clamp screw 44, the conductor cord 53 together with its sad-iron may be separately stowed away until again needed.

The desired degree of lateral resiliency may be fixed by the moulded diametral size that is given to our plastic stanchion. The truncated flat tip area of the Fig. 1 stanchion assembly is preferably held to a size that whether solid or tubular, will afiord a fixedly upstanding cord prop 23 of approximately uniform strength throughout the tapered length thereof when subjected to lateral bending. Either of its forms provides for a compact, low cost base mounting that is simple to fabricate on a productive scale as an elegantly shaped product affording a smooth stanchion surface without unguarded clefts. It is not esfined to the lower stanchion region and affixed.

to the brim ridge 41 when fabricated from laminated metallic spring stock to afiord a wide range deflection without set. A reenforcement of this kind may be located alongside the conductor core in substantial flatwise alignment with the plane of prop fiexure. By the application of such composite materials, the diametral base size of the prop may be considerably reduced over a nonreenforced rubberized plastic.

Other advantages inherent in our improved cord holder will, it is believed, be apparent to those skilled in this art, it being understood that the same underlying principles of fabrication may be widely modified and applied to similar uses other than ironing boards, all without departing from the spirit and scope of our invention hereto-' fore described and more particularly defined in the appended claims.
